The quadratic formula is shown below.

The beauty of the quadratic formula is that as long as your quadraticis in the form ax² + bx + c = 0, where a, b, and c are integers, you can go straight to the answer by simply plugging your values for a, b, and c into the quadratic formula.

It's a good idea to memorize it.

Believe me it's worth it, you'll be using it all the time.

Answer: x = 20

Step-by-step explanation:

Sine when two lines intersect then we obtained two pairs of congruent vertically opposite angles,

Here, 3x + 50 and 6x - 10 are vertical opposite angles made by the intersection of lines,

⇒ 3 x + 50 = 6 x - 10

⇒ 3 x = 6 x - 10 - 50

⇒ 3 x - 6 x = -60

⇒ - 3 x = - 60
